Music Metadata Search

Search in your local music library using quick filter on metadata tags.

My main usage is to find musics I want to play and pipe it to mpv but it can be used for different purposes (see "usage").

music-metadata-search ~/music --where "genre like '%sport%'" | mpv --playlist=-

It will:

• walk in the given directory and parse metadata using music-metadata
• Cache metadata inside a SQlite database using Drizzle ORM
• do a SQL query to filters results
• pipe results

My main objective is to have a CLI tool fast & convenient, for myself. It takes 45s for my library of 150go (5406 files), and then less than 1s using the cache.

Install

npm i music-metadata-search

CLI usage

Generate list of filepath matching where the genre contains "French":

music-metadata-search ~/music/ -g 'French'

Or you can pipe to mpv to play them. Example playlist my new Rock songs:

music-metadata-search ~/music/ -g 'rock' -s "mtime DESC" | mpv --playlist=-

Or you can export an old school French Touch playlist as .m3u file:

music-metadata-search ~/music/ -g 'French' --where 'year BETWEEN 2000 AND 2005' -f m3u > french-touch.m3u

Or getting the "Daft Punks albums before 2000" using JSON output and jq

music-metadata-search ~/music/ -a 'daft' --where 'year < 2000' -f json | jq '[.[].album] | unique'

Use music-metadata-search --help for more information.
